During the rebuild, I did dab 5-minute epoxy over the plug wells as a precautionary measure. The carb was recently disassembled for a clean up, and the epoxy had corroded and had become flaky. It was cleaned off. The wells don't seem to be leaking.

It was noticed during this past dis-assembly that the main well bleed tubes in the air horn were clogged. They were cleaned out using Hobart 770085 Welding Oxy-Acetylene Tip Cleaner. The procedure involves dissembling the top end of the carb, finding the largest tip cleaner that fits inside the bleed tube, and slowly filing away. Keep moving a size up until its all cleaned out.

Another thing that was missed during the first rebuild was the eccentric plastic cam in the air horn that is responsible for the secondary metering rods. It was found during a recent reassembly in the float bowl body, where the key that operates the choke plate is found. The part was ordered from Cliff Ruggles' site. The kit also included new screws for the air flaps.

The procedure replacing the cam involves removing the air flaps and shaft assembly, and is outlined in the images below.

The choke pull off needs replacing regardless of the idle situation. It controls the opening rate of the secondary air valve. It applies force when it has vacuum applied (like at idle ) to the air valve linkage that holds the air valve and everything else attached to it (this depends on the exact carb in question as to what else, if anything, is included) in the proper position.

As you can see it is only a very little bit that the throttle stays open.

and it's almost like the little play there is in the linkage seems to be gone when the engine is running. I can not feel any play when the engine is running.

I really couldn't hear the engine over the wind noise, but Im sure the experts on this forum will come through. Btw, did you consider trying the single or double-spring set up that cobalt327 and Willys36 posted pictures of (posts 127 and 138)?

alrighty,

checked the choke unloader. unplugged it...first put a hose on it and sucked on it, but the unloader doesnt move...

I then plugged the connection to the carb and drove it a bit. But no change.

Still got the annoying high idle when I dont kick the throttle...

I made two short films (As requested) hope you guys can see what I mean...

Here is a photo of the 'better' spring bracket I made for my grandson's Elky. Cut it out of a piece of scrap 1/4" thick aluminum I had lying around. Took all of 30 minutes to make including the polishing. Mounts on front head bolt.

I checked if the fast idle cam is keeping the idle high, but it isnt...what else can it be?

While I don't know the answer to your question, I'm bumping this post up so hopefully someone responds soon. If it is possible, can you make and post a video showing what happens? Maybe two videos, one with engine on and the other with engine off?

OK,

heres some pics of my forward "better" spring setup. Its hard to take pics, but here they are.

I noticed that in my setup my spring was about half an inch shorter stretched in "idle" position then in the carbs original setup.

So today I drilled two more holes too stretch it a little more. I'll take a drive tonight and report back on it.

heavy throttle

check the throttle shaft bushings for wear. that is common problem. the throttle shafts bind because the butterfly valves never end up in the same place twice. thery also leak vacuum so it is hard to adjust the idle mixture. also check all the rest of the linkages and pull offs on the carb. some are affected by the choke so if the choke is still on a little that part of the linkage isn't operative. like the 4bbl lockout won't owrk if the choke is active. grab some carb cleaner/lubricant spray at the parts store and do a little clean up of all the rods etc. if you have a little extra cashola, get a new aftermarket carb and some new distributor weights and springs (recurve the distributor) at the same time. that will perk it up. have to spend a couple hundred though.
good luck,
dsraven

To add to the information. It seems that only when the engine is warmed up, I have the high idle problem, because the throttle linkage last bit has extra resistance. So the last 1-2 mm before it hits the idle screw feels heavy. So heavy when warm, that the springs dont pull it back to full idle, making it idle at about 1000-1100 rpm.
